ADUM4402ARWZ Description

The ADUM4402ARWZ from Analog Devices Inc. is a high-performance, quad-channel digital isolator utilizing magnetic coupling (iCoupler®) technology. Designed for 5,000Vrms isolation, it ensures robust signal integrity in high-voltage environments. Operating at 1Mbps data rate with a 3V to 5.5V supply range, it supports bidirectional logic-level translation while maintaining unidirectional channel communication. Key performance metrics include a 25kV/µs common-mode transient immunity (CMTI), minimizing noise interference, and low propagation delay (max 100ns), ensuring real-time signal accuracy. Packaged in a 16-SOIC tube, it is RoHS3 compliant and rated for MSL 1 (unlimited) shelf life, making it suitable for industrial and automotive applications.

ADUM4402ARWZ Features

• Quad-Channel Isolation: Four unidirectional channels for versatile signal isolation.
• High CMTI (25kV/µs): Superior noise immunity in noisy environments.
• Fast Switching: Rise/fall times of 2.5ns and 40ns max pulse width distortion for precise timing.
• Wide Voltage Range (3V–5.5V): Compatible with 3.3V and 5V systems.
• No Isolated Power Required: Simplifies design and reduces BOM cost.
• 5000Vrms Isolation: Meets stringent safety standards for industrial and medical systems.
• Magnetic Coupling (iCoupler®): Eliminates optocoupler aging issues, offering long-term reliability.
